Like I said, it's only supposed to run on linux; anyway, is it likely
that problems will arise when filenames I have to handle have
basically three sources:

1. already existing files

2. automatically generated filenames, which result from adding an
ascii-only suffix to an existing filename (like xy --> xy_bak2)

3. filenames created by user input

?
If yes, how to avoid these?

Any hints are appreciated
